I don't want three new species. I want one regular beholder, one beholder lich, one Huge beholder, and one gauth. I don't want a swank display case.
How about a pack of umber hulks?
Or my personal favorite, a box of flumph?
QFT. I'd be a lot more interested in mini packs of they were done this way.What I'd be thrilled to buy is an "encounter in a box." For example, if you had a "drow encounter in a box," you could have some drow warriors and spiders, a drow cleric, a drider or two, and a small handfull of grimlock minions. Then have a sheet with a matrix telling you which monsters to include for an encounter of a given level.
That is the sort of product I'd snap up in a heartbeat, even if I already owned some of the minis in the set.
Actually, I spent $35 on just the original Beholder mini when it came out.
